YOOPAI Pro Filament Storage Boxes, Airtight 4-Pack for 1.75 mm Spools

Keep a 3D printing workspace organized by storing each filament spool in its own sealed container. The YOOPAI Pro boxes are designed for single 1 kg spools with a 1.75 mm diameter, giving each spool a secure, well-fitted place between print jobs.

An upgraded silicone sealing system helps shield filament from moisture, dust and changes in the surrounding environment. Reusable desiccants absorb excess humidity inside the boxes, helping keep filament dry and ready for use.

The compact design also supports vertical stacking, so a collection of materials can be arranged neatly instead of left loose on a shelf. With four boxes in the pack, it’s easier to give different spools their own protected storage.

Product specs

• Type: Airtight, single-spool filament storage box
• Capacity: One 1 kg spool per box
• Compatibility: 1.75 mm PLA, ABS, PETG, TPU and other 1 kg filament materials
• Dimensions: 7.87 × 3.03 × 8.07 in without lid, 9.52 × 4.56 × 8.46 in with lid
• What’s included: Four storage boxes and reusable desiccants

The single-spool fit is useful when you want to store materials separately, rather than place several loose spools together in a larger container. Its dimensions are designed to reduce unused internal space, while the stackable shape makes it practical to organize boxes vertically on a shelf or workbench.

Getting the most from it

Place a compatible spool inside its box and use the included reusable desiccants to help absorb excess humidity. The sealing system adds a barrier against dust and environmental moisture during storage, which is especially useful when a spool is not being used between projects. Keeping each material in a separate container also makes it easier to find the spool you need without disturbing the rest of your filament collection.

For example, after printing with PETG, return the spool to its own box with the desiccants in place. The enclosed storage helps protect the filament between sessions, while the four-box format can keep commonly used materials organized and accessible. Compared with leaving spools exposed on an open rack, this approach adds individual sealed storage and moisture control, an open rack may suit quick access, while these boxes are designed for more protected, space-conscious storage.

What’s included

The pack contains four single-spool storage boxes and reusable desiccants for moisture control. Use the boxes to separate and store compatible 1 kg filament spools, then stack them vertically to make more efficient use of available shelf or workbench space. The visible monitoring feature supports checking the storage environment as part of regular filament organization.

When it makes sense

These boxes suit 3D printing setups that use 1.75 mm filament and need a tidy way to store multiple spools between jobs. They bring together individual spool storage, a silicone sealing system, reusable desiccants and a stackable design, helping protect materials from dust and excess humidity while keeping a filament collection easier to manage. A solid pick if you want dedicated, compact storage for compatible 1 kg spools rather than a shared container or an open rack.
